Macbook Pro (Lion 10.7.3) will not connect to Wi-Fi -- persistant 'connection time-out', and fails.
I can see this seems to be a common problem, and it is amazing that there seems to be no consensus (that I can find) on what the underlying problem is.
Here are the basics.... I have two Macbook Pro 13's... Pretty much identical setups (Lion 1.7.3 etc.).
One, works flawlessly connecting to Wi-Fi - whether that is my Airport Express, or any other open or closed networks.
The second, will continually refuse to connect -- to the Airport Express or even a wide-open 802.11b network. It will continually pop up the "connection timeout" erorr, and refuse to connect...
Iphones etc all connect perfectly... Even when connecting to the iPhone hotspot - the same error.
This will happed consistently, until I give up. I can leave it for a day (use ethernet), and come back tomorrow, and voila - it will connect. I may be able to use it for a day or several, but once it decides to 'fail', there is virtually nothing I can do to bring it back... it will continue to fail over and over again.
All updates are applied, I've cleaned out all other networks etc from the list. Tried all civilized things that I can.
Thoughts? Anyone have any other insight? Think this could be a hardware issue? I was thinking to yank the wi-fi module from the working notebook to the non-working one as a test...
Thanks,
Brad
Change your router channel number. Most times this works & is all you have to do.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

I bought 2 new memory card to 4 grams each - replace them in your MacBook Pro 13-inch but it will not turn on - If you are installing a card for 2 and one for 4 d all works - tell me what could be the problem
I assume that you have installed new RAM in your MBP.
It would be helpful if you indicated the EXACT model/year MBP that you have.
What the the RAM specifications that you are trying to install?

My MacBook Pro (OS 10.7.2) will not load some sellers websites that bounce through yahoo.
My MacBook Pro (OS 10.7.2) will not load some sellers websites that bounce through yahoo. Other Macs on same network work fine. I have reset Safari, tried other browsers, eliminated cookies..... to no avail. All computers running 10.7.2. I have reset Safari, tried other browsers, trashed out cookies. This has me baffled. My other macs running the same OS version work fine. Flash is up to date and have done the current software update. Any help please. I have not blocked any sites and am administator for all machines. I have tried signing in as Guest. Nothing works.
After searching other users questions with related problem, I found that VirusBarrier 6 was the issue. Reconfigured settings there and problem solved.

(MacBook pro 8,1) Firmware password will not reset. Resetting PRAM fails.
(MacBook pro 8,1) Firmware password will not reset. Resetting PRAM fails. Resetting NVRAM in Open Firmware fails. Resetting PMU fails. Any suggestions?
Not trying to circumvent any feature or security of the hardware. I am the owner of the hardware, I know the current firmware password. I am simply trying to turn off my current firmware password so that I may reset the PRAM to fix a failed OS install. The instructions to turn off the current firmware password should also include having to enter in the current firmware password as done on previous models with the boot CD. This feature was made available to all models because it is a security must have and it abides by industry-standard security procedures as stated in HIPPA and other ISO standards.

My Mac Pro all of a sudden would not turn on. It beebs 3 times, pauses, and then does it again. I don't think I have downloaded anything recently and I don't know what to do!
3 beeps usually means a Ram problem, have you added or removed Ram recently?
And I will assume that you do not have a Mac Pro, but that you have a portable, a MacBook Pro. -
My iphone 3gs will not connect to itunes and it says that I need to do a system restore. It also says that I need to enter my password on the iphone to connect to itunes but I can not do this because the phone is in emergency phone call mode only.
Turn your phone off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your phone and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a phone in recovery mode. Now you can restore to factory settings.
Unfortunately, the data on your phone is already gone if you're seeing the connect to iTunes logo. -
I have a Iphone 4 gsm (8f190) and it will not connect to itunes and when i put it in recovery itunes will not work. It won't show up when plugged into the computer. Only charges when plugged in the wall or a car charger. I've tried everything imaginable but I can't get the phone to register in iTunes at all.. The phone won't even reset.. when i try and reset EVERYTHING on the phone the apple logo with the progress bar starts to come up but the progress never moves.. PLEASE help me.. I'm at my wits end with this phone and I'm ready to just trash it.

Warning to iPhone users. Do not start the update of the iPhone software using iTunes.
Nonsense, and very misleading advice. I've updated iPhone 3G, 3Gs,and 4 through itunes many times, never had a problem once, not with one single update in nearly 5 years of iPhones. Of course, I've never jailbroken my phones either. Hack your phone and have update problems? I've got news for you, the problems are not a result of iTunes or Apple's updates. -

Dude you have a jailbroken phone as stated in your first post, no need to do a second post.
As per the forum term of service you can't get help here. Use google.
that's the downfall of jailbreaking your phone. -

I have a macbok pro running 10.7.5. My internet has always worked on it but I decided to try changing my router set up - the set up didn't work so I reverted back to the original setup that had previously worked.
Now, I have an Imac running tiger - I can connect to the internet via WIFI or Built In Ethernet with no problem.
When I try to connect to the internet on the Macbook Pro running osx 10.7.5 my internet will not work
Safari Says (You are not connected to the internet) and Google Chrome says (Page is Unavailbe) and lists some trouble shooting options that I tried.
When I go to System prefrences > Network my WIFI and Ethernet both say "Connected" and have a green light next to them.
I have tryed deleting the connections and starting new ones and I have even tried deleting the Location and starting a new one.
Nothing works - no matter what I do, even know the WIFI or ETHERNET says Connected, the internet will not work on the Macbook Pro.
The Internet works fine on my Imac and I have tried everything such as swaping cables but there doesn't seem to be a problem with my internet
or with my router - it all works fine with my Imac running Tiger.
Can anyone help me get my internet working on my Macbook Pro again? Any ideas?Hello ASGR.SYS amd WahWar,
I tried both of your suggestions and neither of them worked.
ASGR SYS - When I tried it your way i got a message saying that the that the diagnostic couldn't repair the problem. It shows the thw WIFI, WIFI SETTINGS, NETWORK SETTINGS, ISP, all turn green. But the Internet and Sever stay red. The thing is, there is nothing wrong with my internet connection as I can connect to the internet on my Imac running tiger, both through ethernet and wireless. When I go to System Prefrences and Ntwork the WIFI and ETHERNET both say "Connected" even know I can't veiw any websites.suggestion
When I tried WAHWAR's suggestion I get a message that says cannot connect to the WIFI network and then it lists your typical trouble shooting tips. Like Make sure you entered the right password and make sure you are in range of the wireless network
Again, just to confoirm - My internet connection is working fne both the WIFI and the Ethernet. When I use it on my IMAC running tiger, everything connects as it should and it works perfectly. But when I try to connect with the MacBook Pro, Even know the connections in the Network settings window show up as "connected" the MacBook still seems to think that my internet connection isn't working at all.
I have tried creating new connections, creating new locations, and I have even gone as far to reset my router and start completely from scratch. The result so far has been the same - the IMAC running tiger will connect - my blackberry and iphone will connect - but the macbook pro running lion will not connect..
I'd apprechiate any other suggestions -
Calendar on MacBook Pro using Mavericks 10.9 will not sync with Google Apps for Business
Ever since the Mavericks upgrade, I have had problems syncing my MacBook Pro Calendar with my Google Apps for Business Accopunt. When Mavericks first came out, I could do a work-around and set up a second CalDev account and that worked for a while. But with the most recent update to Mavericks, in part apparently to solve Google integration issies, the Calendar app will not sync either through the mail account setup in System pref, or by setting up a separate CalDev account. I have no functioning Calendar on my MacBook, thogh the CalDev account option works fine on my iPhone and iPad, and of course all work on the PC with Google Apps Sync.
Appreciate any advice, or better appreciate if Apple were to get this right ASAP.Thank you for your answer, unfortunately that is not the solution. I found the plug-in where it was already properly installed in the Root Level Library>Internet Plug-ins Folder. It was NOT to be found in the [User Name]>Library>Internet Plug-Ins Folder, so I copied it there from the Root Level Folder, Rebooted, deleted all cookies, signed in to Netflix, and I still get the same:
Thanks for installing
Once installation is complete please restart your browser to watch this movie.
So, I tried a complete re-install of Mavericks OSX 10.9, from scratch. I checked all Internet Plug-In Folders and the latest version Silverlight Plug-in is in all of them. Still, I get the same:

Itunes and safari will not connect after installing the last update, but mozilla and internet explorer does.
Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes, and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

Mac Pro Lion 10.7.5 will not receive bluetooth file from Macbook Leopard 10.5.8
Since late 2008, I have been running a 2.2GHz / 3,1 / 4GB MacBook, now at 10.5.8. A few days ago I bought a 2.66 GHz / 1,1 / 6GB Mac Pro, now at 10.7.5. I can not seem to get the Lion Mac Pro to successfully receive a 3.3mb file sent, via BLUETOOTH, from the Leopard Macbook. Sending the file, from the Leopard MacBook, usually, fails and gives the message, "There was an error connecting to the device". A few times I did get an incoming file alert on the Mac Pro and the file seemed to begin coming from the MacBook; however, the estimated time varied wildly and the file transfer eventually failed and displayed the aforementioned message. I have an android 2.3.6 phone and I was able to successfully send the same 3.3mb file to the Mac Pro in a matter of a minute, or so. I may downgrade the Mac Pro to 10.5.8, because I have important software/hardware that may not be supported on Lion, but, right now, I am trying to determine compatibility with my important Leopard software/hardware. For the time being, I want to send files to the Mac Pro via BLUETOOTH, as opposed to any other transfer method.
I don't know the answer to your problem, but until you resolve it do not upgrade OS X.
I would suggest you try a reinstall:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.
